Doug's Greenhouse update

Put the plastic and shade cover up Saturday. Getting real closet to finishing it, if that is possible.

Hi Doug;   Your greenhouse looks great!  Is this a season extending greenhouse or are you hoping to keep it going all winter?

Looking to be a year round greenhouse.

Hi Doug;   What form of heating are you planning for winter?  I did not notice a rocket mass heater in any of your photo's?  
Ha Ha sorry Doug I'm kind of a RMH fanatic...  But seriously I see your going with the warm water barrel method.
They work great as long as you can keep them warm (don't count on the sun in winter) Let them get cold (not frozen just cold) and they will suck up any heat you have, leaving little for your plants.
